None of the defendants are allowed to talk to Fred she would have to go through their attorneys. I think people attribute too much power to Fred just because she owns some successful businesses and a lot of property.
What is Fred going to do? Call up Billy's attorneys and tell them they have to file a bond motion? No, Fred is not calling any shots, the defense lawyers call all the shots. It was Fred's lawyer orchestrating her short video clips and telling her what to say not the other way around. Fred is only as powerful as the attorney she hires. She hired a very good attorney.

I do believe very well that Billy's attorneys have talked to FW. Back in the beginning this was discussed in court, and one of the attorneys said it would be very likely that they would want to talk to the grandmothers. I believe it was one of Jake's. I would have to find the occurrence. JMO
